Lack of any verification or photo or phone verification.
As a result, I've seen numerous illegal content, fake profiles of people pretending to be other people and anyone joining at any age.
Grindr aren't taking ownership of this seriously huge safety concern that is a wide spread issue and not just a odd individual case, as the reviews clearly show.
Their report "system" is none exsiting.
Needs to be passed on to authorities, as this is a safety concern in regards to verification and protecting others.
